摘　　要：基于电荷离散化的事实,运用最小平移算符的性质,计算介观金属双环系统中电荷、电流以及能量的量子涨落,研究影响量子涨落的因素。结果表明:量子电流、量子能谱的量子涨落不仅与介观金属环的电参量、Plank常数有关,而且还明显地依赖于电荷的量子化性质。On the basis of the charge discreteness, the quantum fluctuations fo the charge, current and energy in the mesoscopic metal dual rings are calculated by the minimum shift operator. The effects of the parameters on the quantum fluctuations are investigated. The results show that, taking account of the charge quantization, the quantum fluctuations of the current and energy are related not only with the parameters of the mesoscopic metal dual rings and Plank constant, but also with the charge discreteness.
